Any is better than none, and everyone has the right to defend themselves and their teams.
If no one with alternative perspectives or experiences ever came in, or if they were not accepted and welcomed (albeit they may be rightly challenged and debated) then we may as well be a private Subreddit echo chamber.
The forum is here to enable discussion, debate, and the sharing of knowledge and experience. We may be cynical, but that doesn’t mean we’re closed off to new (tangible) evidence and well structured logic that may generate dissonance between what we thought we knew or believed.
